DUMPING-WAGON RACK.

Specification of Letters Patent.

Application filed October 26,

Patented Mar. 21, 1911.

1909. Serial N0. 524,684.

To all whom it may concern:

lie it known that l, W mms XV. Drinnen, a citizen of the United States,residing at Bartlett, in the county of Ramsey and State of North Dakota,have invented a new and useful Dumping-Wagon Rack, of which thefollowing is a specification.

This invention relates to dumping wagons or racks and its object is toprovide a siniplc structure of this type the body of which is designedto be tilted laterally so as to discharge the load at one side of thevehicle.

Another object is to provide a device of this type having a side paneldesigned to be elevated prior to the dumping of the body whe-rtby thecontents of the body can be discharged without hindrance.

A, still further object is to provide simple mechanism mounted upon thevehicle and which can be operated in any preferred manner for thepurpose of elevating the movable side panel and tilting the wagon bodywhen it is desired to discharge the load.

With these and other objects in view the invention consists of certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claims.

ln the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings, Figure 1 is a side elevation of the body of a vehicleembodying the present improvements. Fig. 2 is a plan view of the sillsand of the actuating mechanism carried thereby, the standards beingshown in section. Fig. 3 is an end elevation of the parts shown inFig. 1. Fig. 4 is a view similar to Fig. 3 and showing the positions ofthe parts during the dumping operation.

Referring t0 the figures by characters of reference 1 designatesparallel longitudinally extending sills/ having upwardly convergingstandards 2 secured to the end portions thereof each pair of standardsbeing held together att-heir upper ends in any preferred manner, as bymeans of caps 3. Brackets 4 extend outwardly from each of the end sills5 which connect the longitudinal sills 1 and a shaft 6 is mounted withinthese brackets and supports sheaves 7 and 8. A laterally extending arm 9is secured to each end sill and extends beyond the side of one of t-helongitudinally extending sills 1 and located between these arms 9 andbearing on the longitudinal sills l, is the bottom '1.0 of the wagonbody. Trunnions 11 extend from the ends of this bottom 10 and bearwithin the arms 9, these trunnions being so located as to permit saidbottom 10 to tilt downwardly across the outer faceof the adjoininglongitudinal sill 1. Any suitable forms of end panels 12 may be mountedupon the bottom 10 and a side panel 13 is fixedly secured upon one sideof the bottoni. The other side of the wagon body is provided with amovable panel 14 provided at its ends with arms 15. These arms extendfrom the upper ends of the fro-nt and rear portions of the panel 14 andare pivotally connected as at 1G -to the adjoining sta-ndards 2, therebeing braces 17 for holding the arms 15 in fixed relation to the panel14.

A shaft 18 extends transversely through the middle portion of the sills1 and is provided at one end with a crank 19 or other suitable meanswhereby the same may be readily rotated. Two sets of ropes or cables 2Oand 21 are secured to this shaft 18, the two sets of cables beingextended in opposite directions from the shaft. Each cable 20 extendsunder a sheave 8 and thence upwardly and over a sheave 22 journaledwithin the upper portion of one of the standards 2, said cable beingsecured at its ends to the bottom portion of the movable side panel 14.The cable 21 of each pair extends unn der the sheave 7 and thenceupwardly over a pulley 23 mounted within the other end standard 2, saidcable being then extended partly around a sheavc 24 which is jour naledon the adjoining end of the bottom 10. The end portion of the cable 21is then extended upward and secured to the standard 2 in which theshea-ve 23 is mounted. The arrangement of the cables is the same at bothends of the structure.

It is to be understood that when the part-s are in their normalpositions the bottom 10 of the vehicle body rests upon both of the sills1 and the side panel 14 bears upon the bottom and closes the side of thebody. It will also be seen that when the panel 14 is thus held in closedposition, it will retain any load placed upon the rack and does notrequire the use of any special fastening devices t-o prevent it fromopening when subjected to the outward pressure exerted by the load. Thecables 21 are preferably slack under normal conditions while the cables20 are taut. It will be seen therefore that when the shaft 18 is rotatedso as to wind the cables simultaneously, the cables 2O will. pullupwardly on the side panel 14k and cause it: to swing about the pivots16 ot arms l5 and after a suiiiciont upward movement of the side panelhas been produced in this manner the cables 2]. pull upwardly upon thesheaves 24: and cause the bottom l() to tilt laterally. The contents ofthe wagon body will thus be discharged trom the side thereof and underthe panel M. By unwinding` the cables from the shaft 18 the foregoingoperation will be reversed and the parts restored to their normalpositions by gravity. It will be seen that the mechanism hereindescribed is very simple in construction and will. not: readily get outof order and is advantageous because of the ease with which it may beactuated and the rapidity of the discharge of the contents of the body.

It is to be understood that itis unnecessary to employ a normally slackcable the movable panel is so mounted relative to the dun'iping body asto move out of the path of said body during the dumping operation andswing back to its normal position as the body returns to its initialposition.

.Vhat is claimed is:

l. A device of the class described including longitudinally extendingsills, standards supported thereby, a wagon body normally bearing on thesills and pivotally connected thereto, a side panel pivotally connectedto the standards, and means for tilting the body to discharge a load andfor simultaneously elevating the panel above the lowered portion of thebody.

2. A device of the class described ineluding longitudinally extendingsills, standards supported thereon, a wagon body normally bearing on thesills and pivotally mounted, arms pivotally connected to the standards,a side panel fixed relative to the arms, normally closing one side ofthe body, a winding device carried by the sills, and means actuatedthereby for tilting the body laterally to lower one side thereof and forsimultaneously elevating the panel ot said lowered side.

A device of the class described including longitudinallyextending'sills, laterally extending arms thereon, a Wagon bodypivotally mounted between and connected to the arms, standards supportedby the sills at the ends of the body,rarms pivotally connected to thestandards, a side panel fixed relative to the arms and normally closingone side of the body, and means tor swinging one side of the body andthe panel of said side simultaneously in opposite direct/ions.

ll. A device of the class described including a supporting structure, awagon body tiltably mounted thereon, standards upon said structure, armspivotally connected to the standards, a side panel iixed relative to thearms and normally closing one side of the body, a winding device, aiexible connection between said device and one of the standards, aflexible connection between said winding device and the movable sidepanel, means upon the body and -movably engaging the flexible devicewhich is secured to the standard, and means for guiding said. flexibledevices during the operation of the winding device for simultaneouslyswinging one side of the body downwardly and the panel of said sideupwardly.

5. A device ot the class described including a main structure, racktiltably mount-- ed thereon, a panel constituting a closure for one sideof the rack, means for simultaneously swinging one side of the raclrdownwardly and swinging the panel of said side upwardly to open the sideof the rack, and connections between the panel and main structure forholding said panel against lateral movement relative to the rack.

In testimony that I claim the toreging as my own, I have hereto aiiixedmy signature in the presence of two witnesses.
